Conspiracy theorist Alex Jones claimed Monday that President Trump is being “covertly drugged,” possibly by the government.

“It’s known that most presidents end up getting drugged. Small dosages of sedatives till they build it up. Trump‘s such a bull he hasn’t fully understood it yet,” the InfoWars host said, offering no evidence of his claim.

“But I’ve talked to people, multiple ones, and they believe that they are putting a slow sedative that they’re building up that’s also addictive in his Diet Cokes and in his iced tea and that the president by 6 or 7 at night is basically slurring his words and is drugged,” Jones continued.

Jones, who in the past has bragged about his communications with Trump, called on the president to get his blood tested by a physician outside the White House.
